The Defiant controls

Two controls regulate the performance of the Defiant: a
primary air control supplies oxygen for the fire, and a
damper directs air flow within the stove to activate and
deactivate the combustion system. (Fig. 31)
Symbols cast into the stove are reminders of the correct
directions for using the controls. The words 'Left' and
'right' in these directions are facing the stove.

maintaining, and reviving a fire.
More air entering the stove makes the fire burn hotter
and faster, while less air prolongs the burn at a lower
heat output level. (Fig. 32)
For the greatest air supply and maximum heat output
(but the shortest burn time), move the lever toward the
front of the stove. For a fire that will last longer with
less heat, move the lever toward the rear of the stove.
a Damper Directs air Flow
within the Stove
The damper handle on the left side of the stove oper-
ates the damper to direct air flow within the stove.
The damper is open when the handle points to the
rear, enabling smoke to pass directly into the chimney.
The damper must be open when starting or reviving a
fire, and whenever the griddle or doors are opened.

The damper is closed when the handle points forward.
Smoke travels through the non-catalytic combustion
system where it can be further burned, before passing
up the chimney. (Fig. 33)
The damper should always be either fully open or
fully closed. There are no intermediate positions.
when closing the damper, be sure to pull firmly
enough to snap the handle into the locked position.
